This is an Exhaust Fluid Pump designed to manage the Selective Catalytic Reduction (SCR) system in Volvo equipment. It precisely injects diesel exhaust fluid (DEF) into the exhaust stream to reduce harmful nitrogen oxide (NOx) emissions, meeting stringent environmental standards. Failure may manifest as a check engine light, reduced engine power, or increased DEF consumption.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of failure is often an illuminated DEF system warning light on the dashboard. If ignored, the system may enter a reduced power mode or require more frequent DEF refills. Continued operation with a faulty pump can lead to non-compliance with emissions regulations.
Before installation, thoroughly flush the DEF lines to remove any debris that could clog the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing.
Inspect the DEF filter and lines for any signs of blockage or contamination when replacing the exhaust fluid pump.
